Configuring a DNS Server for Enhanced web authentication
If you use a host name to configure access to a web server on which customized login web pages are stored, you must first configure a Domain Name System (DNS) server to resolve the web server's host name into a target IP address. (If you specify an IP address to configure a web server, it is not necessary to configure a DNS server.)
For example, the following web server host name requires the configuration of a DNS server to resolve the host (webserver1) and domain name (accounts.hp.com) into a target IP address.
To configure
switch access to a DNS server to support the use of a host name in
the aaa port-access web-based ewa server
command,
see the “Troubleshooting” chapter in the management and configuration
guide for your switch.
